Hi!
You talk about the "semantics" of NUMA balancing between global, cgroup and process. While I read the kernel doc "NUMA Memory Policy", it occur to me that we may have a "NUMA Balancing Policy".
Since you are the reviewer of CONFIG_NUMA_BALANCING. I would like to discuss the need for introducing "NUMA Balancing Policy" with you. Is this worth doing?
